EBB now suitably greased, will give it a spin to see how quiet it is. I’ve ordered a Bushnell EBB which arrives tomorrow just in case! I’ve got 32:20 on the bike at the mo which is equivalent to the 34:20 that I ran on the 26″ bike last year, which I thought was spot on. Bike and kit is lighter this year however the contours also appear much closer. I bought a 21T sprocket for the event but haven’t fitted it as I need to make my chain longer, What d’ya reckon. I’ve got used to riding the wrong gear as I did the Kielder 100 last year with my 2:1 rato on the 26″ and spent about 90% of the time in too tall a gear :oops:.
BTW my route also takes me through Penrhyn Dyfi and Maesywerngoch
